For the year 2025, these are the most trafficked books in the Math library:

Calculus (OpenStax) (616k+ visitors)
Applied Finite Mathematics (Sekhon and Bloom) (245k+ visitors)
Elementary Algebra (LibreTexts) (142k visitors)

Anyone have any recommendations of other good books? These are just the ones that are most commonly hit upon by searches online, not necessarily the ones that are most adopted.

I am significantly biased, but the modification of the OpenStax Calculus I and II textbooks that sit in the Cosumnes River College library are some of the best. All the mistakes from the OpenStax books have been fixed, material has been added and edited, and the order has been changed to closely match one of the most popular publisher-pushed calculus texts.
